PROBLEM TO BE SOLVED: To provide a method for producing a plastic lens which can produce the lens in a short time without wasting a raw material resin for plastic molding and makes the storage/control of a molding member easy. SOLUTION: When the raw material resin for forming the plastic lens injected into a cavity formed by a first molding member 11, a second molding member 12, and a spacer 13 covering the peripheral parts of the molding members 11 and 12 is cured, the second molding member 12 is composed of a flexible sheet, and a position in the surface direction of the flexible sheet is adjusted to conform with a desired molding surface by a positional controller 30. Since the plastic lens is produced by curing the raw material resin for molding the plastic lens which is injected into the cavity formed by the molding members 11 and 12, the spacer 13, and a pair of molding members, even when the surface shape of the plastic lens is different in every product, the difference can be eliminated by displacing the second molding member 12 in accordance with the surface of the plastic lens.
